【问题描述】：

我想将图片发布到 facebook 和 twitter。我对 twitter 很好，但对使用 SLComposeViewController 类的 facebook 不满意。没有添加图像，我可以将文本和 url 发布到 facebook。问题是当我使用添加图像时，我无法发布此图像以及文本、网址。 SLComposeViewController 在我发送时显示图像、文本和 url。我有正确的 appId，我没有收到任何错误。但问题仍然存在。我不知道问题出在哪里。请帮帮我。

        [self showListOfFaceBookAccountsFromStore];
                if([SLComposeViewController isAvailableForServiceType:SLServiceTypeFacebook])
            
                SLComposeViewController *mySLComposerSheet = [SLComposeViewController         composeViewControllerForServiceType:SLServiceTypeFacebook];

                 SLComposeViewControllerCompletionHandler __block completionHandler=^(SLComposeViewControllerResult result)

                     NSString *output;
                    switch (result) 
                        case SLComposeViewControllerResultCancelled:
                            output = @"ACtionCancelled";
                            break;
                        case SLComposeViewControllerResultDone:
                            output = @"Post Successfull";
                            [self dismissViewControllerAnimated:YES completion:nil];

                    [alert show];
                 ;

                [mySLComposerSheet addImage:[UIImage imageNamed:@"images4.jpg"]];
                [mySLComposerSheet setInitialText:@"I am developer."];

                [mySLComposerSheet setCompletionHandler:completionHandler];
                [self presentViewController:mySLComposerSheet animated:YES completion:nil];

    ACAccountStore *accountStore = [[ACAccountStore alloc] init];
    ACAccountType *accountType = [accountStore accountTypeWithAccountTypeIdentifier:ACAccountTypeIdentifierFacebook];


    if( [SLComposeViewController isAvailableForServiceType:SLServiceTypeFacebook] )

                if([account username]==NULL)
                    [self facebookAlert];
                 else 



                

            
            else
                  NSLog(@"Read permission error: %@", [error localizedDescription]);
            
        ];
     else 
        [self facebookAlert];
    

【参考方案1】：

我在我的项目中使用了下面的代码来发布它工作正常的图像。

    if([SLComposeViewController instanceMethodForSelector:@selector(isAvailableForServiceType)] != nil)
    
        if([SLComposeViewController isAvailableForServiceType:SLServiceTypeFacebook])
        

            SLComposeViewController *controller = [SLComposeViewController composeViewControllerForServiceType:SLServiceTypeFacebook];

            SLComposeViewControllerCompletionHandler myBlock = ^(SLComposeViewControllerResult result)
                if (result == SLComposeViewControllerResultCancelled) 

                    NSLog(@"Cancelled");

                 else

                
                    NSLog(@"Done");
                

                [controller dismissViewControllerAnimated:YES completion:Nil];
            ;
            controller.completionHandler =myBlock;

            [controller setInitialText:@"Check out my Christmas Gift!"];
            [controller addImage:@"gift.jpg"];

            [self presentViewController:controller animated:YES completion:Nil];

【讨论】：

感谢重播。我已经添加了你的代码，但我没有得到图像。但是当我删除 addImage: 方法时，我的脸书上收到了消息。

你只需检查图片是否存储在facebook相册而不是墙上

@PrasadG 我加了两个教程看看吧

感谢您的建议。你是对的。这些照片在相册中。

这段代码没有解决我的问题。检查***.com/questions/20881429/…

【参考方案2】：

我查看了互联网，发现最近 1 或 2 天有一些与此问题相关的讨论，它们似乎与 Facebook 错误有关。因此，如果您的代码成功将消息和图像发布到 Twitter，请不要担心！你做得对。

  I have resolved through open present-view controller in navigation-bar.it may help you.

 SLComposeViewController *controller = [SLComposeViewController   composeViewControllerForServiceType:SLServiceTypeFacebook];
    [controller setInitialText:shareFrom];
    [controller addImage:self.photoImageView.image];
    [controller addURL:[NSURL URLWithString:dayCareWebsite]];
    dispatch_async(dispatch_get_main_queue(), ^ 

        [self.navigationController presentViewController:controller animated:YES completion:nil];

    );
